Revisit the generated ovirt hostname var
The vms role makes a variable called _vms_ovirt_hostname
available to playbooks using the role to refer to the currently managed oVirt host (basically the name of the VM in oVirt). This is useful, but since adding linting checks, it triggers warnings since it doesn't fit with the loop variable name standard __{role_name}_
.
For now, we're ignoring those errors, but it did make me think that maybe a better variable name (w/ no leading underscores?) might make more sense.
